Mike, if I remeber well... They sent you a download link only. Before every thing, you have to go to their site (they say that in the mail ?), register with the serial number they have sent to you and then download v 2. Then they will send you another e-mail what looks like this one : ____________________ ""Thank you for registering Deep Exploration. Below you will find your Authorization Code, username and password. To complete the activation of your license select Register from the Help menu and enter your Serial Number and Authorization Code when prompted. The username and password will give you access to the Registered User area that contains product updates, the latest plugin files and more. Please ensure that you keep this information in a safe place and remember that your username and password are not to be used by anyone other than yourself. Order ID/Serial Number: xxxxxxxxxxxxx Authorization Code: xxxxxxxxxxxxxxxxxxx Username: blabla Password: xxxxxxxxx (Note: both the username and password are case sensitive) ..........."" _______________________ When you install, it will ask you if you agree to install in c:program filesDeepExploration just say OK (your original 3Dexploration is in the folder 3Dexploration or XDimensions). You can keep it, but you will not like it anymore:-) Hope this helps:-) Guitta
